To all 'whom it may concern:

Be it known that we, WILLIAM E. ATON and WILLIE J. A'roN, citizens 0f the United States, residing at Milburmin the county of Carlisle and State of Kentucky,.have invented certain new and useful Improvements in Agricultural Implements, ofwhich the following is a specification. l

Our invention relates to agricultural .implements and has f orits object the provision of a simple and inexpensive implement by the useyof which the surface'of the ground will be thoroughly pulverized and a proper seed bed formed. The invention also has for its object to provide. means .whereby the ground-engaging members may be set at any desired angle and held in the set position.

The invention is illustrated in the accompanying drawings, in which- 4 Figure 1 is a plan view of an .agricultural implement embodying .our improvements;

Fig. 2 is a side view of the same.

In carrying out our invention, we employ a frame consisting of longitudinally. disposed side or frame bars l on which transverse tooth bars 2 are mounted for rocking movement. The tranverse bars 2 may conveniently be tubes and are fitted in seats or bearings 3 formed in the frame bars 1 whereby the latter will support the tooth vbars and permit rotation of the same. Draft chains 4 are secured to the front ends of the frame barsl and a whifiietree 5 is connected with the front ends ofsaid chainsy whereby draft animals may be connected with the implement to draw the same over a field. Itis to be understood, however, that the machine may be coupled toy a tractor andthe larger sizes will be equipped with a coupling especially designed to connect with a tractor.

In the arrangement shown in the accompanying drawings, four transverse tubular bars 2 are employed, the two forward bars having secured thereto scraper blades 5 having their ends 6 deflected laterally so that they will cut into the surface soil and turn the same to one side and the rear two bars are equipped with straight harrow teeth 7, as shown. The teeth 7 may have their Shanks inserted through the tubes 2 and clamped blades 5 have their front ends coiled .or ywrapped around the tubes, as shown at 8, and secured by bolts 9 inserted through the tubes and the saidl coiled ends andequipped with suitable retaining nuts.k rlhe blades 5 are somewhat resilient so that they will'yield slightly to the draft of the implement but willcut into and slightly turn the soilV and theblades 0n the first tooth bar have their ends turned in one direction while the ends of the blades `on the second tooth bar extend in the opposite direction wherebyy the entire surface of the field will be treated. The blades 5 at their pointsof attachment to the transverse bars y2, are preferably `given a quarter turn or twist so as to cause the longitudinal edges ofsaid blades to be presented to the ground and thus facilitate cutting the soil. The straight teeth 7V will, of course, merely pulverize the soil and leave the surfacevrin a level conditionso that a good seed bed will be prepared. The longitubular bars and are pivoted to short bars 15 forming the bottomof `cpiadrants l'which may be engaged by latches 17 upon the re.-

spective levers inthe usual manner.v The rear `quadrant has its rear end extended into 'a link 18 which is pivoted 'at its rear end to a crank arm 19 rising from the rearinost tubular bar 2, while the forward quardrant 16 has its front end similarlyextended to form a link 2() which is pivoted to a crankarrn 21 secured to and. rising from the foremost tubular bar. It will be understood that the crank arms 19 and 21l`a`rel arrangedparallel to the levers 14 and 13, respectively, and the pivotal connectionof the levers to thebase bars of the quadrants completesan extensible or foldable frame which acts to set the har- 'lfOW' teeth andthe blades ai any' desired angle and to hold them at that angle. The en s of the short bars 15 of the quadrants are preferably bent or folded over the upper longitudinal edges Vof the links 18 and 20, as shown. 1

If desired, rollers 26 may be mounted on the front transverse bar 2'for supporting the free end of the harrow.

If the lever 14, for instance, be swung forwardly the tubular-bar 2 to which the said lever is secured will be rotated about its own longitudinal axis and the teeth 7 thereby set at a greater or Alessangle to the ground. The pivotal connection of the lever to the bar 15 will cause the said bar to also move forwardly andu this movement will be, of course, transmitted directly to the quadrant 16 and the link 18 so that the crank arm 19 will also be swung forwardly and the'rearmost tubular bar 2 rocked or rotated so thatv the harrow teeth thereon will be given the same inclination as that given the teeth on the preceding tubularV bar. The bars carrying the blades 5 may be likewise ladjusted by manipulation of the lever 13 and it will be understood that the blades 5 and the teeth 7 may be used together ors'eparately as the nature of the soil may demand. The bar 10 upon which the seat-carrying standard is secured is Ifitted to the tubular transverse bars in the same manner that the longitudinal .end bars lare fitted thereto so that there will invention, wh at spaced side barsra plurality `of transversek bars journaled for rocking movement in the side bars, blades secured to and extending rearwardly from certain of the bars, harrovv teeth carried by other of said bars, crank arms vprojecting upwardly from the outer transverse bars, quadrants each having one end thereof extended to form a link pivotally connected withthe adj acentcrank arm and with its base portion'secured to the adj acent link, and .operating leversrigidly setoV cured to theV inner transverse bars and pivotally connected 'to the base members ofthe quadrants for rocking the: transverse bars and changing the angle ofthe bladesand harrow Vteeth with respect to the ground.;
